Hi there,
I will summarize all the details and provide you with clear, concise proposal.
I am a Full stack developer with 10 years of experience.
I have worked on several similar projects like you have described, and can deliver quality work to tight deadlines.
You can see an example of one of those projects in my portfolio here: https://www.freelancer.in/u/singhkirti1989
I can generally work upto 8 hours per day.
I'm interested to hear more about the project and about the complete requirements.
If you award me the project I'd be very happy to discuss this further and get started for you as soon as possible.
Thanks! Kirti
